Instructions
1. In a small pot, melt chocolate, butter, sugar and milk over low heat. Stir. When chocolate is melted and smooth, turn off heat.
2. Gently stir in fresh peppermint leaves. (The peppermint must be completely dry when you drop it into the chocolate.)
3. Let cool for about 10 minutes.
4. Pour the mix into a 9-by-9-inch baking pan and place the pan in the freezer until set, about an hour.
5. Using a sharp knife, carefully cut the fudge into squares. (You may wish to rinse the knife under hot running water several times.)
